Thou Shall Not Be a Flipper

Reading the Haftorah this Shabbat brought to mind scenes from the 2004 Republican National Convention in Madison Square Garden in New York City where attendees where waving pictures of John Kerry chanting “Flip-flop, flip-flop…” referring to Kerry’s ever changing position on the war in Iraq (“First I voted for it, before I voted against it”) and other political issues. Former Governor of New York State, George Pataki, said there, “This year, we will win one for the Gipper, and they will lose one with the Flipper.” Kerry lost, as flippers usually do. This Haftorah (weekly portion of Prophets read publicly in Synagogues) starts with an astonishing statement of Elyahy Hanavi (Elijah the Prophet), “How long will you waver between two ideas? If the Lord is G‑d, follow Him, and if the Baal, follow him.” (Melachim-I [...]

Global or Local?

And let them make me a Sanctuary that I may dwell among them (Ex. 25:8) In modern physics, there are two paradigms usually expressed as locality and nonlocality. Theoretical physics was born when Isaac Newton published his Philosophiæ Naturalis Principia Mathematica in 1687, where he formulated his laws of motion and the universal law of gravity. The law of gravity says that two masses attract each other proportionally to the product of their masses and inversely proportionally to the square of the distance between them. This law said nothing about the nature of the gravitational interaction, it did not explain the mechanism of this attraction at a distance. Newton was bothered by the question of how one body can act on another body far removed from it with nothing in between, i.e., the notion of “action [...]

Convergence of Science and Torah

Convergence of Science and Torah

The Torah portion of Yitro (Ex. 18), is the high point of the story of Exodus—the giving of the Decalogue on Mount Sinai. In a strange digression, the progressive narrative of the Exodus from Egypt is interrupted by the side story of Jethro (Yitro), the father-in-law of Moses, who comes to Sinai desert to join the Jewish nation. After hearing Moses’ account of all the miracles G‑d performed for Jewish people, Jethro exclaimed: Now I know that the Lord is greater than all deities. (Ex. 18:11) Jethro said confidently, “I know,” because, as the chief priest of Midian, he indeed knew all pagan cults and all deities worshiped in his time. Moreover, in antiquity, priests were expected to possess all secular knowledge as well (sadly, it is no longer the case). They needed to [...]

Manna – Superposition of All Tastes

While traveling in the Sinai desert, Israelites were fed by the heavenly bread – the manna. The Torah portions – parshat Beshalach – states that raw manna tasted like wafers that had been made with honey: וַיִּקְרְאוּ בֵית-יִשְׂרָאֵל אֶת-שְׁמוֹ, מָן; וְהוּא, כְּזֶרַע גַּד לָבָן, וְטַעְמוֹ, כְּצַפִּיחִת בִּדְבָשׁ. And the house of Israel called the name thereof Manna; and it was like coriander seed, white; and the taste of it was like wafers made with honey. (Ex. 16:31): However, in Numbers, it says that it tasted like cakes baked with oil: כְּטַעַם לְשַׁד הַשָּׁמֶן The taste of it was as the taste of a cake baked with oil. (Num. 11:8) The Talmud (Yoma 75b) reconciles this discrepancy by explaining that the tastes varied depending who ate the manna – to small children it tasted [...]

Splitting of the Sea

Do you like riddles? Here is a riddle – what do these two figures represent in the context of Exodus? No Idea? How about a hint? Still no idea? Okay, here is the answer: Yes, the first figure represents two doorposts and the lintel marked with the blood of Passover sacrifice, as it says: וְלָקְחוּ, מִן-הַדָּם, וְנָתְנוּ עַל-שְׁתֵּי הַמְּזוּזֹת, וְעַל-הַמַּשְׁקוֹף--עַל, הַבָּתִּים, אֲשֶׁר-יֹאכְלוּ אֹתוֹ, בָּהֶם And they shall take of the blood, and put it on the two side-posts and on the lintel, upon the houses wherein they shall eat it. (Ex. 12:7) The second picture is of the splitting of the sea, as it says: וַיָּבֹאוּ בְנֵי-יִשְׂרָאֵל בְּתוֹךְ הַיָּם, בַּיַּבָּשָׁה; וְהַמַּיִם לָהֶם חוֹמָה, מִימִינָם וּמִשְּׂמֹאלָם And the children of Israel went into the midst of the sea upon the dry ground; and the [...]

Riddle — the answer

And the answer is... (drum roll, please) Yes, the first figure represents two doorposts and the lintel marked with blood of Passover sacrifice and circumcisions as is says: וְלָקְחוּ, מִן-הַדָּם, וְנָתְנוּ עַל-שְׁתֵּי הַמְּזוּזֹת, וְעַל-הַמַּשְׁקוֹף--עַל, הַבָּתִּים, אֲשֶׁר-יֹאכְלוּ אֹתוֹ, בָּהֶם And they shall take of the blood, and put it on the two side-posts and on the lintel, upon the houses wherein they shall eat it. (Ex. 12:7) The second picture is of the splitting of the sea, as it says: וַיָּבֹאוּ בְנֵי-יִשְׂרָאֵל בְּתוֹךְ הַיָּם, בַּיַּבָּשָׁה; וְהַמַּיִם לָהֶם חוֹמָה, מִימִינָם וּמִשְּׂמֹאלָם And the children of Israel went into the midst of the sea upon the dry ground; and the waters were a wall unto them on their right hand, and on their left. (Ex. 14:22) And both have to do with time. But this is a [...]

Riddle — a hint

There were some good ideas expressed in the comments. Close, but no cigars. Here are some hints for you folks: 1. These two pictures express ideas described in the current and the previous sidrot (weekly Torah portions); 2. Don't focus on the differences in these pictures, focus on similarities. 3. The answer has to be expressed in two psukim (verses) -- one from the last parshah and the other from the current parshah describing each respective picture. 4. Last but not least, here are these pictures again with some details:

Mezuzah and Time

Bo: Exodus 10:1 – 14:16 The Erev Shabbat parshat Bo (the Eve of Sabbath of the week when we read the Torah section Bo) 2014 was my lucky day – I seem to have found an answer to a nagging question of many years. During several years from 1989 to 1996, I had been working on a book on Mezuzah. This was not a book about halachot (ritual laws) of mezuzah – there were many books on that subject – this was a book about the meaning of mezuah – its significance in Jewish history, philosophy, ethics, and mysticism. By 1996, the book was finished and I signed a contract with the leading publisher of English Judaica – Jason Aronson. I was supposed to deliver the finished manuscript in a few months, but [...]

Carpe Diem

Carpe Diem

As we have discussed in the post, It’s the time, stupid, Pharaoh never got the message that it’s all about mastery of time. To make sure Jews did get this message, G‑d gave them the very first commandment—the commandment of keeping time, of marking new months: This month shall be unto you the beginning of months; it shall be the first month of the year to you.(Ex. 12: 2) It is important to note that Jews were not only commanded to keep time, they were commanded to “make” time. Indeed, in Biblical times, the new month was not calculated according to a calendar, as it is done today, it was proclaimed by a Bet Din (an ecclesiastic court) based on the testimony of two live witnesses, who observed [...]

It’s the Time, Stupid!

It’s the Time, Stupid!

There is a continuous thread about the mastery of time that weaves through the last chapters of the book of Genesis (Bereshit) and continues through the beginning of the book of Exodus (Shemot). The story of Joseph’s incarceration ends with his successful interpretation of the dreams of the Pharaoh’s chief butler and the chief baker. Joseph's genius was not only in interpreting ordinary objects (tendrils of grapes and baskets of bread) as symbols of the units of time but in understanding that the engagement in time (manifested in the chief butler’s personally squeezing the grapes into the cup and placing the cup in Pharaoh’s hand) symbolized life for the chief butler and the passivity of the chief baker (who dreamt of baskets of bread sitting on his head, with birds eating from the baskets) [...]

Sensing Spirituality

Sensing Spirituality

It is unsurprising, then, that spiritual phenomena have never been experimentally detected in a laboratory setting. Spirituality, by definition, is non-physical. Consequently, no physical laboratory equipment can detect anything spiritual; it is inherently "neutral" to it. Physical elements do not interact with the spiritual, much like a neutron does not couple with an electromagnetic field, or an electron with a strong nuclear field. So, what does interact with spirituality? Only spirituality itself.

I Am Who I Am: Conversation at the Burning Bush

I Am Who I Am: Conversation at the Burning Bush

…And behold, the thorn bush was burning with fire, but the thorn bush was not being consumed." (Ex. 3:2) Every theologian worth his salt along with many philosophers, from Plato and Aristotle to Descartes and Kant, attempted to prove the existence of G‑d. Tomas Aquinas, for instance, offered not just one but five “proofs”! Others, such as Hume and Nietzsche, tried proving the opposite. Little did they understand that proving the existence (or nonexistence) of G‑d is a fool’s errand. Here are at least ten reasons why G‑d's existence cannot be proven (or disproven): The existence of G‑d cannot be proven because… G‑d doesn’t “exist,” not in the ordinary sense of existence anyway. One can say that something exists only so long as it may exist or may not. By stating that something [...]

Moses — the First Scientist

Moses — the First Scientist

And the angel of the Eternal appeared unto him in a flame of fire out of the midst of a bush; and he looked, and, behold, the bush burned with fire, and the bush was not consumed. And Moses said: "I must turn aside, and investigate this wondrous phenomenon, why the bush is not burnt." Exodus 3:2-3 In this Torah chapter, Moses sees a strange sight – a burning bush not consumed by fire. His scientific curiosity is aroused and he does what any good scientist would do—he goes to investigate this “wondrous phenomenon.” Moses was the first scientist recorded by the Bible. We, scientists, chase after wondrous phenomena to investing their nature. However, we often do it with arrogance, caring our own agenda and preconceptions. Torah teaches us otherwise, as G‑d warns [...]

Interpreting Dreams

Interpreting Dreams

In the Torah portion Vayeishev (Gen. 37:1–40:23), we read about Joseph interpreting dreams of the Pharaoh’s chief butler and the chief baker: And the chief butler told his dream to Joseph, and said to him: “In my dream, behold, a vine was before me; and in the vine were three tendrils...” And Joseph said unto him: “This is the interpretation of it: the three tendrils are three days.” (Gen. 40:9-12) How did Joseph know that three tendrils are three days? The story repeats itself with the chief baker: When the chief baker saw that the interpretation was good, he said unto Joseph: “I also saw in my dream, and, behold, three baskets of white bread were on my head…” “This is the interpretation thereof: the three baskets are three days.” (Gen. 40:16-18) Joseph interpreting [...]

Body Chemistry

Body Chemistry

Reading the Torah, sometimes, can give a false impression of reading a story, albeit the greatest story ever written. This Divine drama involves colorful characters, sophisticated plots, jealousy, sibling rivalry, deception, struggle, suffering, and every human emotion. The profound insight brought to light by the Kabbalah—the esoteric interpretation of Torah—was the realization that the human drama played out by Biblical characters is also a mashal—a metaphor or an allegory—that alludes to spiritual forces interacting in higher worlds. Actually, from the point of view of Jewish mysticism, whatever happens down here, first takes place in the spiritual worlds and only later[1] manifests itself in the physical realm. Every Biblical hero, from the point of view of the Kabbalah, is an embodiment and personification of a supernal spiritual archetype. Thus, physical Abraham, in the Kabbalah mysticism, is [...]

Entangled Sisters

Entangled Sisters

The story of entangled twins is continuing in the Torah portion Vayeitzei (Genesis 28:10–32:3.) Structurally, it is very similar to the story in the previous Torah portion, Toldot (see “Entangled Twins”). In this portion, we again read about two entangled siblings—albeit, this time, sisters—about deception and spontaneous symmetry breaking. Two sisters were Rachel and Leah. Moreover, according to Midrash, Rachel and Leah were also twins (Seder Olam Rabbah).[1] As inseparable twins, they were “entangled,” as it were. They were somewhat opposite—one introvert, the other extrovert; one beautiful, the other, perhaps not so much (she had “weak eyes”): Now Laban had two daughters: the name of the elder was Leah, and the name of the younger was Rachel. And Leah’s eyes were weak; but Rachel was of beautiful form and fair to look upon (Genesis 29:17). Rachel and [...]

The Entangled Twins

The Entangled Twins

Entanglement is often called the most baffling and the most quintessential aspect of quantum mechanics. What is entanglement, in a nutshell? Two particles born out of one reaction (or two particles that interacted through a collision) remain connected, no matter how distant from each other. A change in the status of one particle instantaneously causes a change in the status of the other particle. Einstein called it "spooky action at a distance." Entanglement is often associated with a certain symmetry and corresponding conservation laws. For example, the law of conservation of angular momentum requires that the spin (the quantum-mechanical analog of the angular momentum) of two entangled particles always point in the opposite directions. This means that, if two entangled particles have their spin in a state of superposition of Up (↑) and Down (↓), and we collapse [...]

Maarat HaMachpelah – Double Cave

Maarat HaMachpelah – Double Cave

Give me the Machpelah (double) Cave Genesis 23:9 The first legal acquisition of land in Israel takes place in this Torah portion, Chayei Sarah, when Abraham purchases a double cave, Maarat HaMachpelah, in the city of Chevron (Hebron) as an ancestral burial plot. Today, the immense rectangular structure built over the cave more than 2000 years ago during Herodian era is the oldest house of worship in the world in continuous use. Biblical commentator Rashi explains that the cave was called Machpelah (lit., double) because it had two structures—an upper chamber and a lower chamber. (Another explanation given in the Talmud relates the name of this cave to thee couples buried there—Abraham and Sarah, Isaac and Rebecca, and Jacob and Leah. According to Kabbalah, Adam and Eve are buried there as well (Zohar, Ruth 96). Cave of the Patriarchs [...]

Witnesses – See and be Seen

By the mouth of two witnesses, or three witnesses, shall the one liable to death be put to death; he shall not be put to death by the mouth of one witness. (Devarim-Deuteronomy 17:6) I wrote about witnesses in my earlier post imaginatively called Witnesses. Deuteronomy restates many mitzvoth (commandments) introduced earlier, which is why it is also called Mishneh Torah – the repetition of Torah – the portion Shoftim-Judges restates the law of witnesses first introduced in in the book of Numbers, portion Massei. So we shall revisit this fascinating subject. The Judgment of the Sanhedrin: "He is Guilty!" (1892 painting by Nikolai Ge) I. An accused criminal and a Schrödinger cat Most criminals are convicted in the US based on circumstantial evidence. Rare is the case when a jury gets to hear an [...]
